Would this bill also remove all implementations of, say, RSA from the Internet?
I'm going to make a wild ass guess, and say they haven't thought that far ahead.
The Arab world traditionally has had great mathematicians. I'm sure there is a bright young student in university right now who could write a good enough PGP implementation for the right price.
Nitpick, but most have them happen to have been Persians, colonized by the Arabs.
Oh for sure, but a majority of Persians during the Islamic Golden Age. I have no horse in that race, just a random fact I noticed while reading about each.
